There’s also a lot more guidance around now, for example, from bodies like the Chartered Institution of Building Service Engineers (CIBSE)..
Fabrication of structures and components for structures up to 15 stories high using steel, aluminium and stainless steel.Execution Class 2 requires welds to be completed to ±0.4mm on steel and ±0.0 on aluminium.
Certification is for the full factory control procedure including procurement, processing, fabrication, storage, Q&A and delivery with documentation at every stage.Accuracy in pre engineered interfaces.The level of the bespoke design in traditional projects makes it difficult to properly design every interface, leading to variability between interfaces on-site and the need for ad hoc changes.
However, trades at different points in the process don’t necessarily have access to the early decision-making rationale, so there can be unanticipated consequences of these forced ad hoc changes.. For example, façade installers have reported that they spent 40% of their time undertaking site surveys and using shims and packers to fill in the gaps between their manufactured unitised systems and traditionally built superstructures.This example is particularly pertinent given the crucial role façades play in fire stopping and compartmentation..
If the BSA onus is on ensuring the design doesn’t change from specification to delivery, then the exactness of the design and the tolerances is crucial..
The higher degree of accuracy and innovation in platform components ensures that what was designed and modelled is much more likely to be what is installed on site, with no need for site based problem-solving/adaptions vs. what has been designed and tested..It’s worth stressing again that standardisation in construction is not a negative, and it’s not unique to platform design either.
We’ve found that most clients want a certain level of standardisation.The Department for Education knows exactly what the best performing teaching space looks like.
Most residential developers have a pattern book of apartments, which are best suited for their needs.They don’t want to design from scratch each time.
